400 : Bad Request

[maryamayat]

When I open this notebook , I get this error:

400 : Bad Request {'model_id': 'cca6545d689344a68abd93983b6655ef', 'version_major': 2, 'version_minor': 0} is not valid under any of the given schemas Failed validating 'oneOf' in display_data['properties']['data']['patternProperties']['^(?!application/json$)[a-zA-Z0-9]+/[a-zA-Z0-9\-\+\.]+$']: On instance['cells'][14]['outputs'][1]['data']['application/vnd.jupyter.widget-view+json']: {'model_id': 'cca6545d689344a68abd93983b6655ef', 'version_major': 2, 'version_minor': 0}

However, it works if I open it through github (this url).
